Bellow Globe Valve

Purpose
Globe valve with bellow seal acc.to ANSI is applicable to the cutting and connection of pipelines medlum that are used in various indus-tries such as peroleum,chemical industry,pharmacy.chemical fertilizer,electric power industry etc under nominal pressure of CLASS150-1500LBS and working temperature of-29-350.

Structural features
1.This product has logical structure.reliable seal.excellent performance and nice design.
2.The seal surface is build-up welding with Co hard alloy,which is attrition-resistant,corrosion-resistant,has good friction resistant and long life.
3.The stem is quenched and tempered.and its surface is treated by nitriding treatment,thus it has good corrosion resistant and friction resistant.
4.It has double seal capability.thus is more reliable.
5.The stem may show the position of lift,thus it is chearer.
6.The part material,flange and butt weld end dimension may be selected accordng to current operating condition and users'requirement,so that meet the requirements of various engineering.
